- Absolute magnitude (Wikipedia)
In astronomy, absolute magnitude (M) is a measure of the luminosity of a celestial object on an inverse logarithmic astronomical magnitude scale. An object’s absolute magnitude is defined to be equal to the apparent magnitude that the object would have if it were viewed from a distance of exactly 10 parsecs (32.6 light-years), without extinction (or dimming) of its light due to absorption by interstellar matter and cosmic dust. By hypothetically placing all objects at a standard reference distance from the observer, their luminosities can be directly compared among each other on a magnitude scale. For Solar System bodies that shine in reflected light, a different definition of absolute magnitude (H) is used, based on a standard reference distance of one astronomical unit.
- Belltown, Seattle (Wikipedia)
Belltown is the most densely populated neighborhood in Seattle, Washington, United States, located on the city’s downtown waterfront on land that was artificially flattened as part of a regrading project. Formerly a low-rent, semi-industrial arts district, in recent decades it has transformed into a neighborhood of trendy restaurants, boutiques, nightclubs, and residential towers as well as warehouses and art galleries. The area is named after William Nathaniel Bell, on whose land claim the neighborhood was built.
